In DL, memory maps are comparatively simple, so we blow out all possibilities. In Do-more, there are nearly 50 possible documentation records for 'D0' alone. To deal with this, we only show existing records and elements which have been referenced in the program. Since we suspected that people would want to be able to document a range of Xs like they had in the past, we added the ability to add references. The purpose of the asterisk is to identify references vs actual records.
I'm sure there is room for improvement, but we felt it was important to draw a clear distinction between stuff actually the database and simple references.
